Definitions

  • This invention relates to an electrical connector assembly for electrical connection between conducting wires and an electromagnetic valve mechanism, and in particular a connector assembly that prevents fretting corrosion between terminals thereof and the terminals of an electrical device having large amplitude vibratory movements such as antilock braking system magnet valves.
  • the latter would be particularly advantageous as it would allow the connector assembly to be manufactured in a semi automated or fully automated procedure and supplied as a complete assembly to the automobile manufacturer. In such a procedure, costs would not only be reduced, but the assembly could also be made in a more reliable manner as the connector assemblies could be individually tested at their site of manufacture.
  • the objects of this invention have been achieved by providing an electrical connector for connection to an electrical device, the electrical connector mountable to the device and securely holdable thereagainst by spring means, whereby the spring force is greater than the total frictional force between mating device and connector contacts.
  • an electrical connector assembly comprising a casing to which the connectors are mounted by spring means, and a cover mounted to the casing whereby the assembly is a single unit that can be coupled to a single unit electrical device such as a magnet valve assembly comprising a casing and a corresponding number of magnet valves.
  • FIG. 1 is a cross sectional view through an electrical connector assembly connected to a partially shown magnet valve assembly
  • FIG. 2 is a cross sectional view of another embodiment of an electrical connector assembly connected to a partially shown magnet valve assembly.
  • an electrical connector assembly generally shown at 2 is assembled to a magnet valve assembly generally shown at 4.
  • the magnet valve assembly 4 comprises a casing 6 having a rim 8 with a sealing member 10 thereon, and magnet valves 12 having each a pair of electrical tab terminals 14.
  • the electrical connector assembly comprises a casing 16 having a magnet valve receiving face 18, a wire receiving face 20 and connector receiving cavities 22 extending therebetween, a sealing member 24 mounted around the periphery of the wire receiving face 20, a cover 26 fixable over the wire receiving face, and a plurality of electrical connectors 28 mounted via springs 30 in the cavities 22.
  • the electrical connector 28 comprises a housing 32 having a mating face 34, a terminal receiving face 36 and terminal receiving cavities 38 extending therebetween, and also comprising receptacle terminals 40 matable with the tab terminals 14 of the magnet valves 12.
  • the connector housing 32 also comprises a spring abutment shoulder 42 therearound and integral resilient retention lances 44.
  • the coil spring 30 is either mounted within the casing cavity 22 against a shoulder 46 thereof at the terminal receiving side 20, or around the connector housing 32 such that it abuts the shoulder 42 thereof.
  • the connector housing 22 can then be inserted into the cavity 32 with the terminal receiving face 36 of the connector housing 32 first being inserted at the mating face 18 of the casing.
  • a polarizing lug 48 on the connector housing cooperates with a slot 50 in the casing 16 to position and prevent rotation of the connector 28 therein.
  • the connector 28 is inserted until the resilient lances 44 are inserted past the shoulder 46 whereby they resiliently bias outwards therepast, thereby retaining the connector in the cavity 22, particularly in opposition to the spring 30 which in this position is slightly compressed thus pushing the lances 44 against the casing shoulder 46.
  • Terminals 40 crimped to conducting wires 52 can then be inserted into the terminal receiving cavities 38, the terminals 40 being retained by locking lances 54 abutting against shoulders 56 within the cavities.
  • the seal 24 is provided around the rim of the casing.
  • the seal 24 is provided with wire receiving (cavities) holes 58 that are joined to the cover mating side 60 of the seal via a thin slit 62 that the wire resiliently biases apart when being inserted therethrough into the wire receiving (cavities) holes 58.
  • the seal 24 is compressed in such a manner that the slits 62 compress tightly together, and the wire receiving (cavities) holes 58 compress around the wires 52 such that the connectors 28 are tightly sealed from the exterior.
  • the cover 26 is also provided with V-shaped slots 64 having a knife edge profile 66 that digs into the wires 52 for retention thereof against a pulling force on the wire 52 from the exterior.
  • the cover 26 can then be secured by some well known latching means available in the prior art such that it is pressed tightly against the sealing member 24.
  • the connector assembly 2 as described above, can thus be manufactured and assembled at a location different to that of the magnet valve assembly 4.
  • the magnet valves 12 are disposed within the casing 6 in such a manner as to receive the connector assembly 2 whereby the tab terminals 14 of the magnet valves 12 are upstanding for reception of the connector assembly receptacle terminals 40.
  • stopping means 70 of the connector housing 32 abut the magnet valves when the tab terminals 14 are fully inserted into the terminals 40, whereby further mating of the magnet valve assembly 4 towards the connector assembly 2 causes the magnet valve 12 to push against the connector housing 32 and resiliently bias the connector 28 against the spring 30, thereby further compressing the spring.
  • the valve casing 6 can be latched to the connector casing 16 via a well known latching mechanism (not shown) whilst compressing the seal member 10 that is disposed around the periphery of the casing therebetween.
  • the connector 28 thus abuts the magnet valve with a compression spring force, whereby this compression spring force must be greater than the frictional force of the mating terminals 14 and 28 so as to ensure that the connector 28 is always abutting the magnet valve 12.
  • a strong inertial force might cause the connector 28 to move away from the magnet valve 12 whereby it would not return thereagainst because the frictional force would be greater than the returning spring force. Further inertial forces however could cause the connector 28 to be pushed back against the magnet valve 12. This movement however would be undesirable and defeat the object of this invention.
  • the magnet valves 12 serve, for example, to prevent locking of an automobiles wheels during braking. If a wheel suddenly stops rotating, the magnet valves are actuated, opening and closing the valves in rapid succession to release the brake fluid pressure of the brake discs thus unlocking the wheels. This rapid succession of opening and closing the valves creates large mechanical shocks to which the magnet valves are subject, whereby the magnet valves 12 may vibrate with amplitudes of around one millimeter.
  • the terminals 40 which could be similar to those disclosed in European patent application 0492479 are designed to avoid fretting corrosion for a certain level of vibration, however the large amplitudes created by the magnet valves cannot be absorbed and might either cause fretting corrosion or fatigue rupture of the terminals 40.
  • the above connector assembly eliminates fretting corrosion and/or fatigue rupture of mating terminals that are subject to large vibratory amplitudes.
  • the connector assembly 2 can be assembled as a separate single unit at a separate location to that of the magnet valve assembly 4 and then rapidly and simply mated thereto, the assembled magnet valve assembly and connector assembly being sealed off from the exterior.
  • FIG. 2 another embodiment is shown, whereby many aspects are similar to that of the embodiment of FIG. 1 except for the terminal wire connecting construction. All similar features to those of the embodiment shown in FIG. 1 will be denoted with the same number but with a prime.
  • the terminals 40 of the embodiment of FIG. 1 are simply crimped to the conducting wires 52 and then inserted into the cavities 38 of the connector housing 32.
  • the terminals 80' comprise an insulation displacement wire contacting section 82' having an insulation displacement slot 84'.
  • the connector 28' comprises a cover 86' that is latchably received over the terminal receiving end 36' of the connector.
  • the cover 86' has wire holding clips 88' integrally molded thereon that serve to provisionally hold the conducting wires 52' and stuff them into the insulation displacement slots 84' for electrical contact therewith.
  • the wires 52' are thus electrically connected to the terminals 80' by first clipping the wires to the wires clips 88' of the cover 86' and then simply closing the cover over the connector housing 32' until the latching means 87' engage.
  • the terminals 80' can thus be mounted to the connector housing 28' separately from the wires 52' and the wires 52' can be rapidly and simply connected to the terminals by clipping them onto the cover without requiring any special preparation of the wire ends. All other features and assembly steps are similar to those described in the embodiment of FIG. 1.
